to that class ofshellslwhich areprovided' with mouthpieces that project some distance beyond theci arette body,such cigarettes beingcomrnov y termed Russian cigarettes. It is the general racticeV at thepresent time to em loy an ad lesive substance for the. pur ose o uniting the` mouthpiece tothe:

she but this method-of keffecting the union of the parts has been found toentail numerous disadvantages, both in thefrnanufacture of ythe articles, as wellasin the lcompleted articles themselves.` Inasmuch as'the'shells and mouthpieces are turned out in quantities by machines the use `of adhesive has a tende ency to` soil theseveral parts fofthe machine with which it comes in contact andin time will clog the operative ,parts thereof fand moreover as the `adhesive also comesin contactvviththe shells at such parts where no` adhesive is required, `many .shells are rendered unusable for this' reason. Again hav# ing reference to ,the completed `shell and mouthpiece joinedfby adhesive, when such united shells and mouthpieces are permitted to remain unfilled with tobacco for any length of time, the adhesive dries or decomposes, losing its adhesive roperty, andv when filling is attempted a argepercentage of the mouthpieces becomes disengaged from their shells and thus-are rendered defective, if indeed not entirely useless. Thisy disadvan. tageous feature is especially prominent-in shells into which the tobacco 1s introduced through the mouthpiece. These shells are sold in large uantities and are .done upfin bundles, eachqbundle containin lthe desired number of shells, say, for eXamp e, 200.` The purchasers are generally smokers who make their o'wn cigarettes, and the practice is to place a bundle of such Vshells on a table, mouth iece u spread the finelyy cut tobacco over t e she s (the bottoms of which are closed) and then by suitable'manipulation to work the tobacco by hand into `theindi'vidual "speeicjtioofnetters Patent.

shells. `lf nowany such mouth iece is loose vfrom 4its shell, slight pressure o' the hand is sufficient to force the mouthpiece down into Y the shellv (which is made'of very thin paper) lcausing the shell to close over the mouthpiece and prevent the admission of tobacco,

thus spoilin that particular shell, and in fact renderingte entire' package or bundle ofshells useless l Owing to the transparency and very small quantityof paste em loyed for each shell it is virtually impossib e to detect defects of 'the kind referred to eXce t by actual use,

and in Ythis manner not o y does the manufacturer frequently lose trade, but the cost of manufactureis also materially increased.

*When adhesive is used in the manufacture A of the cigarette shells `and mouthpieces, three materials'enter into the manufacture, namely,

thecigarette paper, `the sti paper for the mouthpiece material and the paste. The

pastebeing liquid or semi-liquid it is obvious that` there is considerable difficulty in handling the same in a satisfactory manner, and

the handling thereof entails the expenditure When which gives the most trouble in( manufacture is not used. Theonly two materials whichV `1t is necessary to handle being the cigarette paper andthe mouthpiece material, and by omitting the use'of paste, the manufacture of the shells and mouthpiecesproceeds more expeditiously, requiring less labor, less time 'and less cost.

VVHaving 1n mind the foregoing objections to the present method of manufacture, one object of my invention is to provide a method of producing cigarette shells with attached mouthpieces in which the use of adhesive for effecting union of the two members is entirely dispensed with. i Another object is to so join the twomem- "bers that their accidental relative displace- U ment or separation Will be prevented.

\ A further object is to provide a method of manufacture whereby an increased output and more perfect product will result than is. possiblefunder present manufacturing conditions. j

` -Stated in general terms, the invention con- .sists in applying pressure to, or radially distortingat one or more points the material of either the mouthpiece or of both the shell and mouthpiece in such manner as to form an interlock, as it were, which prevents both relative movement and separation of the parts.

For the purpose of illustrating the invention I have appended the accompanying sheet of drawing wherein Figures l, 3, 5, 7 and 9 are longitudinal sectional yviews of shells and mouthpieces joined according to my invention, and Figs. 2, 4:, 6, 8 and 10 are corresponding cross sectional views each being taken on the line- AB of the longitudinal sectional view to which it corresponds.

In carrying out my invention I employ a shell a which usually consists of thin light weight cigarette paper and insert into the same the mouthpiece b, which is shorter than the shell and closely fits against the same. The mouthpiece material is fairly stiff and may be made of any appropriate substance. When the shell and mouthpiece are thus contiguously placed depressions c or c are made at one or more places in either the mouthpiece material or in both the mouthpiece and shell by means of suitably applied pressure thus forming internally or externally disposed projections by means of which the shell and mouthpiece are firmly united without the use of adhesive substance of any kind.

It will be understood that the invention is susceptible of embodiment in the most varied forms and that the forms shown in the drawing are intended to serve merely as illustrations. In Figs. l and 2 two externally disposed rojections are shown, the material of both s ell and mouthpiece being pressed outwardly. Figs. 3 and 4 are the reverse of the two preceding figures in that the projections extend inwardly. In Figs. 5 and 6 the material of the mouthpiece only has been pressed outwardly, the shell itself remaining smooth throughout its length, the union in this form of the invention being brought about by the pressure applied in any suitable manner at the points c, whereby the shell is so closely pressed against the mouthpiece that separation or displacement is prevented. In Figs. 7 and S pressure has been exerted upon the outer periphery of the shell and mouthpiece causing adhesion and depression of the shell and mouthpiece, the inner periphery of the latterremaining smooth throughout. Figs. 9 and 10 illustrate the appearance of an article of the kind where both external and internal pressure has been applied to produce the oppositely disposed depressions c and c in both shell and mouthpiece material.

The invention may be practiced either by hand or by machinery, the latter method being preferable as greater pressure is attainable in this manner, and as the interlock, in certain forms of the invention is produced only by pressure of the shell against the mouthpiece or vice versa.

A very valuable feature in connection with my invention is the facility afforded by the depressions or projections for the reception of advertising features, inasmuch as it is possible and usual to place upon these projections or depressions suitable trade or faetory marks, initials or ornamental features as desired by the dealers or consumers.`

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. As a new article of manufacture, a conibined shell and mouthpiece, having a distortion in either thereof, to form an interlock therebetween.

2. As a new article of manufacture, a combined shell and mouthpiece, the material thereof being distorted, whereby an interlock between the said shell and mouthpiece is formed.

In testimony whereof I have affixed my signature in presence of two witnesses.
